What is Voltage Drop?Voltage drop is the decrease of electrical potential along the path of a current flowing in an electrical circuit. Or more simply, a “drop in voltage”. Voltage drops occur due to the internal resistance of the source, passive elements, across conductors, across contacts, and across connectors are undesirable because some of the energy supplied is dissipated.The voltage drop across an electrical load is proportional to the power available to be converted in that load to some
